Nonetheless, I want to Sing

12-year-old girl Mitsuki Kouyama dreams of becoming a singer and of reuniting with her childhood friend, Eichi Sakurai. However, she has sarcoma, a tumor in her throat. A pair of shinigami, Takuto and Meroko, emerge from Mitsuki's wall, arguing and not realizing that Mitsuki can see them. They are surprised, but introduce themselves and explain that Mitsuki only has one year left to live.
